Specification of Letters Patent.

Serial No. 471,709.

T 0 all whom it may concern:

Be it known that I, ALEXANDER NOBLE, a citizen of the United States,residing at Rock Springs, in the county of Sweetwater and State oflVyoming, have invented certain new and useful Improvements inIncubators; and I do hereby declare the following to be a full, clear,and, exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in incubators andcomprises various details of construction, combinations and arrangementsof parts as will be hereinafter fully described and then specificallydefined in the appended claim.

My invention is clearly illustrated in the accompanying drawings, which,with the letters of reference marked thereon, form a part of thisapplication and in which Figure 1 is a perspective View of theapparatus, showing the egg trays partially withdrawn from the casing,parts of the apparatus being removed to better illustrate thearrangement of the circulating flues about the casing. Fig. 2 is asectional perspective view. Fig. 3 is a perspective View of the rearportion of the casing, showing the tines through which air is adapted tocirculate. Fig. 4 is a detail perspective View of a rack or support forthe casing. Fig. 5 is a detail perspective view of a guard member. Fig.(5 is a detail View of a closure for the opening in one side of thecasing, and Fig. 7 is a detail View showing the manner of supporting anegg tray.

Reference now being had to the details of the drawings by letter, Adesignates a rack having a recess A in its front wall adapted to receivethe flue 13 having a gauze B over the end thereof, so that foreignmatter will not pass into said flue. The flue passes rearward a shortdistance, then rises and communicates with the space intermediate thecasing C and the outer covering or shell D. Upon reference to thedrawings, it will be observed that there are channels D formed in theouter faces of the opposite side walls of the casing C, which channelscommunicate with each other, also channels E formed in the outer face ofthe top of the casing and through which air is allowed to circulate asindicated by arrows. Ducts G communicate between the channels or ducts Dand a transverse duct G and channels or ducts G formed in the outer faceof the roar of the casings communicate with the channels E, all as shownin the drawings and as indicated by arrows. A flue F leads from thetransverse channel G- and up through which outside air is drawn forventilating the apparatus.

The front of the casing is provided with a hinged door A, havingpreferably glass panes therein, and egg trays I slide within the casing,being supported upon the strips K, one or more of which may be providedto hold the tray at different heights. A tray L is inserted within thecasing and is covered with a gauze wire and upon the edges of. said trayL, said strips K are supported, the latter having pins K which engageholes in the sides of the tray L. A closure N is fitted in the recess inthe front wall of the casing and is designed to protect the glass doorand is held in place by means of buttons N. A suitable guard member,designated by letter O, is slipped down over the top of the coveringabout said casing and affords means for preventing the covering ofmanure from falling over the front end of the apparatus. At the frontend of the casing is a flange Q, against the rear face of which theupturned end of the covering R extends, as seen in Fig. 2 of thedrawings, and T designates a covering, preferably of metal, whichextends over the marginal edge of said flange Q and the upturned end ofthe covering 1%. A handle S is provided near the rear end of thecovering of the casing and affords means whereby the latter, whendesired, may be conveniently carried.

In operation, it is my plan to utilize the heat due to chemical actionin a manure pile to furnish heat for incubating the eggs in myincubator. This is accomplished by covering the outer shell with manureof a suit able thickness so that the heat will radiate through theapparatus and afford the requisite degree of ten'lperature for thedesired purpose. By the provision of the flues about the casing, air isallowed to circulate freely about all of the faces of the casing, aswill be readily seen.

lVhat I claim to be new is An incubator having communicating channelsformed upon the sides, top, bottom and end thereof, a casing about saidincubator casing, a door frame at one end of the 0215- 10 and spacedapart therefrom, a flue formed 111 mg, and a recessed guard plateextending said casing and leading to the space underover and about theends of sald door frame.
